title = "Other Situations Involving Group Matrices",

abstract = "This chapter sketches various situations in which the tools described in this book have appeared. They are: 1.The characterization of those class functions on a group which are group characters.2.The use of group matrices in the theory of group rings.3.The application of group matrices to the theory of cogrowth of groups.4.Work of Poincar{\'e} on differential equations.5.The connection between factors of the group determinant and Chern classes.6.The appearance of the group matrix as a Gram matrix for tight frames with a symmetry group, which have appeared in the theory of wavelets.7.The theory of 3-manifolds.8.Control theory and electrical engineering.9.The algebra defined by considering the k-classes under multiplication.",
